[Sewage sludge].

Tijdschrift voor diergeneeskunde, 1987
Current knowledge of sewage sludge is reviewed, particular reference being made to the possible effect on the health of herds of cattle. The following measures should be urgently and seriously considered: more effective watching of sewage disposal; assessments on sewage disposals, related to the costs of alternatives; stricter checks on diffuse sources

Lipid profiling in sewage sludge

Water Research, 2017
High value-added reutilization of sewage sludge from wastewater treatment plants (WWTPs) is essential in sustainable development in WWTPs. However, despite the advantage of high value reutilization, this process must be based on a detailed study of organics in sludge.

Pyrolytic characteristics of sewage sludge

Chemosphere, 2006
In this study, a number of different sewage sludge including sludge samples from industrial and hospital wastewater treatment plants were characterized for pyrolysis behavior by means of thermogravimetric analysis up to 800 degrees C. According to the thermogravimetric results, five different types of mass loss behaviors were observed depending on the ...

Feasibility of wet-extraction of phosphorus from incinerated sewage sludge ash (ISSA) for phosphate fertilizer production: A critical review

, 2020
Incinerated sewage sludge ash (ISSA) is produced worldwide where incineration is used to manage sewage sludge. ISSA contains significant amounts of phosphorus (P) with high recovery potential, and may contribute to mitigate the global P supply problem ...

Mycoflora of activated sewage sludge

Mycopathologia, 1976
Thirty-eight species of fungi were identified in pure culture after isolation from activated sewage sludge by serial dilution. Nine species and genera were identified that had not been previously reported. In 1963, Cooke (1) published an excellent laboratory guide on the identification of fungi from polluted water, sewage, and sewage treatment systems;

Trace elements in sewage sludges

Journal of the Science of Food and Agriculture, 1972
AbstractAnalyses of 42 sewage sludges from rural and industrial towns in England and Wales show very large concentrations of certain trace elements. Total contents of 5% Zn, nearly 1% Cr and Cu and 0.5 % Ni were found in certain dried sludges. Total contents of Cu, Sn and Zn and, to a lesser extent, Ag, Bi and Pb were much greater than the levels of ...
